Control Board
The control board located in the dishwasher door is the brain of the dishwasher. It is connected
directly to the membrane keypad, sending and receiving information to and from the user through
visual outputs such as LEDs and a numeric display as well as audio tones. The control board
manages the operation of the power board located in the base of the unit, turning on and off
various components at the required time. It also receives data directly and indirectly from sensor
inputs on the power board that help govern the timing and operation of the various cycles.
LED Status Indicator
A 3-color status LED is located on the bottom of the door on ED models. (It is an optional accessory
on ID models.) This option is provided, since in many installations, the membrane keypad will
not be visible and the operating status of the dishwasher will be unknown to the user. A blinking
green light indicates the unit is running normally. Solid green or blue indicates that the unit
has successfully completed the desired cycle and can be unloaded. Solid blue indicates that
the required heat and time requirements have been met to sanitize the dishware (as per NSF
Standard.) It is not necessary that the sanitize option be selected for this light to be illuminated at
the end of a cycle nor will the LED turn on necessarily if the sanitize option has been selected. The
blue LED will only be illuminated if the time and temperature requirements have been satisfied.
The solid blue or green LED will turn off once the door is opened for unloading then closed.
